Be it known that we, HARRY W. HANCOCK and Cimnnus H. JARvIs, citizens of the residing` at Charlotte, in the State of Michigan, have and useful Improvements in Tank-Valves; and we do hereby declare the following to be a full, clear, and exact-description of the "invention, such as will enable others skilled in the art to which to make and use the same. This invention relates to an improvement county of Eaton,

, in valves, especially adapted fornse in connection with gasolene tanks of automobiles.

In vall gasolene tanks there is a certain amount of water which is separated from the 'tom of the tank.

gasolene and which normally lies on the bot- After the supply of gasolenc has become exhausted this water has heretofore been drained by means of a suitable valve.

Often-times when running automobiles the supply of gasolene has become exhausted therewith which will permit of a limited- .quantity of gasolene to and as a result the machine is leftwithout fuel. e

The principal object of our invention is to provide a valve having means assoclated be drawn from the tank in lorder that the operator y,may know that the supply is becoming exhausted.

A still further obj ect of the invention is to provide a. devicefor the purpose described in which means are'provlded for permitting.

the balance of the gasolene to lbe withdrawn.

Another object of the invention is t0 provide a device of the character described byy -mcans of which the tank can be drained of the water, thus eliminating the necessity of employing an additional valve for this purpose.

A still further object of the invention is to provide avalve seat and turning plug of novel construction by means of which the three operations can Vbe made. I

'lVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed outv in the claims hereto appended; it being understood that various changesin and minor details of construction, within the scope of the claims, may be resorted to withshown) the form, proportion, size out departin from the spirit or sacrificing any of the-a 'vantages of the invention.

improved valve associated therewith, Fig. 2 i is a vertical sectional view through the valve,

Like reference numerals indicate corresponding parts throughout the several views. Q i

Referring to thev drawing 5 designates a valve casing having an upwardly extending boss A6 which is exteriorly threaded at its end as shown b y7 and provided with an interior bore 6B. -Formed 1n the casing isa transverse seat 8 adapted to receive a turningplug 9. Ali-interiorly threaded boss 10 orming the drain outlet extends downwardly from' the casing and communicates with the valve seat by means of a passage 11. Arranged within the bore 6 of the boss `6 is an upwardly extending pipe 12, ther lower end 13 thereof being seated in a correspondingly sized seat 14 which is formed in the valve casing. The exterior diameter of this lpipe 12 is less than the interior diameter of the boss 6. Thus it will be observedv that a chamber is formed between the pipe and the bossG. Communicating with the valve-seat 8 and the interior of the pipe 12 is a port 15.` Formed in the valvevcasing and 'communicating with the chamber between the pipe and the boss '6 is a laterally extending passage 16 which in turn communicates with a vertical passage 17, the lower end of which communicates with the valve-seat 8 and ata point directly in rear of the port- 15, said passages 16 and 17 forming a port which communicates with the bore 6a and the valve seat- 8. Integral with and laterally projectingfrom the casing is a main outlet boss 18. This boss is preferably interiorly threaded for receiving one end of a pipe 19 which in 'turn communi- Cates with the carbureter of an engine (not Communicating with the interior of said boss 18 and with the valve-seat 8 is a passage 20 and this passage is disposed in alinement with the vertical passage 17 above the valve seat. is a radially extending pas- 1a gasolene tank 25 andthe pipe 12 extends Will drop down to thevtop of the pipe 12.

sition the balance of the gasolene in the tank will then flow through the passage between the pipe 12 and the boss 6, through passages described. The valve or turning-plug 9 is formed with a longitudinal passage 21 and communicating with said passage and with sage 22. This passage 22 is adapted to register with either the passage 11 or 15 for a purpose hereinafter more fully described. The valve is furthermore provided with radially extending passages 28 and 24, which are arranged substantially at right angles to one another. These passages are adapted to coact with either the passage 17 or with both of said passages 17 and 20.

The boss 6 is threaded into the bottom of ,23 in the valve and thence through the out` let pipe to the carbureter as will be readily understood. Should it be desired to entirely cut-off the supply of gasolene the operating handle is turned to the Off position. In

munication between both the drain outlet and the main outlet.

What is claimed is 1. A tank valve for the purpose described, comprising a casing formed with a bore constituting a drain inlet, said casing being also provided with a Valve seat, an inlet pipe having one end seated' within the bore and communicating with the valve seat and havthereinto fora suitable distance. Arranged around the valve 9 and projecting from the valve casing is an enteriorly threaded boss 26 to which is secured a name-plate 27 upon which suitable indicating means, such as Drain Off, Reservoir and On, are shown.' Associated with the turningplug 9 is an operating handle 28.

From the foregoing whenever it is desired to drain the tank of water the operating handle and consequently the valve will be positioned as shown in Fig. 2 of the drawing. In this position the water will pass down through the chamber between the pipe 12 and the boss 6, through` passages 16 and 17, through passages 23, 21 and 22 of the valve and thence through passage 11 and on out through the drain-pipe. After the tank has been filled in order to supply the earbureter with gasolene the voperating handle is turned toa posit-ion diametrically opposite from that shown in Fig. 2 of the drawing. As a result the gasolene will enter the pipe 12, pass through passage 15, thence through passage 22 of the valve, along the longitudi nal passage 21, through the radially eXtending passage 24: and into the outlet pipe. After a certain amount of gasolene has been used the level of the gasolene in the tank ing, a port communicating with said drain inlet and with the valve seat, said casing being also provided with a main outlet and a drain outlet, and amulti-ported rotary valve mounted in the valve seat for controlling the flow of liquid between the inlet pipe and the main outlet and the drain inlet and the drain outlet.

2. A tank valve for the purpose described a counterbore, the bore forming a drain inlet, said casing being further formed with counterbore and having its other end extending beyond the easing, a passage formed in the casing and communicating with the pipe and the valve seat, a main outlet for the pipe formed in the casing, a port formed in the casing and communicating with the bore and the valve seat, an outlet for the drain inlet formed in the casing', and a multi-ported rotary valve mounted in the valve seat for controlling the flow of liquid between the inlet pipe and the main outlet and the drain inlet and the drain outlet.

In testimony whereof we atlix our signatures in presence of two witnesses.

As a result no gasolene will be fed'to the carburetor and in consequence thereof the engine will stop and by incans of this the operator will be notified that the supply of gasolene in the tank is becoming exhausted. The operator at this point'turns the operating handle to a mid-way position orto the position indicated by the word Reservoir in Fig. 1 of the drawing. Thus in this p0- Witnesses:
